The description of strong interaction physics of low-lying resonances is out of the valid range of perturbative QCD. Chiral effective field theories (EFTs) have been developed to tackle the issue. Partial wave dynamics is the systematic tool to decode the underlying physics and reveal the properties of those resonances. It is extremely powerful and helpful for our understanding of the non-perturbative regime, especially when dispersion techniques are utilized simultaneously. Recently, plenty of exotic/ordinary hadrons have been reported by experiment collaborations, e.g. LHCb, Belle, and BESIII, etc. In this review, we summarize the recent progress on the applications of partial wave dynamics combined with chiral EFTs and dispersion relations, on related topics, with emphasis on ππ, πK, πN and scatterings.

具有手征有效场论和色散关系的分波动力学综述
低位共振的强相互作用物理描述超出了微扰 QCD 的有效范围。已经开发了手性有效场理论(EFT)来解决这个问题。分波动力学是解码基础物理学并揭示这些共振特性的系统工具。它非常强大,有助于我们理解非微扰机制,尤其是在同时使用色散技术时。最近,实验合作报告了大量奇异/普通强子,例如 LHCb、Belle 和 BESIII 等。在这篇综述中,我们总结了分波动力学结合手征 EFT 和色散关系的应用的最新进展,在相关主题,重点是ππ , πK, πN和散射。
